Representing written vowels in university students with dyslexia compared with normal hebrew readers

The study investigates dyslexic and normal Hebrew readers’ perception of words containing a vowel letter in different orthographic and morphological contexts. In the first experiment, 72 undergraduate education students (half diagnosed with reading disabilities and half normal readers) were asked to judge pointed words with different morphological structures with and without the grapheme W. Half of the words had consistent (obligatory) W and half had inconsistent (optional) W. In the second experiment, the same procedure was repeated using the same words without pointing marks. Response latencies and accuracy were measured. In both experiments, dyslexic readers did less well than normal readers. They had lower scores on accurate lexical decisions and they took more time over these decisions. They also exhibited some deviant patterns, indicating that they cannot make use of orthographic and morphological cues that are available to normal readers, especially in the pointed experiment. Processing pointed words placed a heavier cognitive burden on the dyslexic readers. These findings are in line with other studies of adult dyslexic reader/writers, and support a reading / spelling processing model, which claims that internal orthographic representations of words are increasingly strengthened with each exposure during reading, but not all graphemes are strengthened equally. The general implication is that the ambiguities that exist in the relationships between orthography, phonology, and morphology underlie spelling knowledge, and are particularly difficult for dyslexic readers.     

Are they using my feedback? The extent of students’ feedback use has a large impact on subsequent academic performance

Feedback is known to have a large influence on student learning gains, and the emergence of online tools has greatly enhanced the opportunity for delivering timely, expressive, digital feedback and for investigating its learning impacts. However, to date there have been no large quantitative investigations of the feedback provided by large teams of markers, feedback use by large cohorts of students, nor its impact on students’ academic performance across successive assessment tasks. We have developed an innovative online system to collect large-scale data on digital feedback provision and use. Our markers (n = 38) used both audio and typed feedback modalities extensively, providing 388 ± 4 and 1126 ± 37 words per report for first- and second-year students, respectively. Furthermore, 92% of first year and 85% of second-year students accessed their feedback, with 58% accessing their feedback for over an hour. Lastly, the amount of time students spent interacting with feedback is significantly related to the rate of improvement in subsequent assessment tasks. This study challenges assertions that many students do not collect, or use, their feedback. More importantly, we offer novel insights into the relationships between feedback provision, feedback use and successful academic outcomes.     

The Turner syndrome: cognitive deficits, affective discrimination, and behavior problems

Individuals with sex chromosomal anomalies are known to be at increased risk for learning problems and in some cases social or behavioral problems. Girls with an absent or structurally abnormal second sex chromosome (the Turner syndrome) have been found to have cognitive problem solving deficits and immature, inadequate social relationships. The present study attempted to link cognitive and social problems by assessing the girls' ability to process affective cues. 17 girls with karyotypes consistent with a diagnosis of Turner syndrome were compared to a group of 16 short-stature girls of comparable age, verbal intelligence scores, height, and family socioeconomic status on the Affective Discrimination Task, which required interpretation of affective intention from facial expression. The results revealed that the Turner syndrome girls were less accurate at inferring facial affect than the short-stature controls. Analyses revealed that the Turner syndrome girls performed more poorly on spatial, attentional, and short-term memory cognitive tasks and had more psychosocial problems than the short-stature controls. Ability to discriminate facial affect may be another area of cognitive weakness for girls with the Turner syndrome and may underlie the psychosocial problems found in this sample.     

The contextual nature of university-wide curriculum change

We explored the relationships between social contexts and factors that promoted and inhibited curriculum change at two universities. Thirty interviews were analysed using a general inductive approach to identify factors and forces in three social contexts (lecturer, departmental, and institutional). Curriculum change was characterised by six forces: ownership, resources, identity, leadership, students, and quality assurance, each composed of factors that differed in their direction (enabling or inhibiting) and/or intensity (strong or weak). Academic developers should find the approach and lessons learned useful for planning interventions and identifying where they may encounter resistance or enablers in the process of change.     

Fraction interventions for struggling elementary math learners: A review of the literature

Understanding fractions has been a pervasively difficult skill for struggling math learners, yet it is essential for success in secondary level mathematics skills. The present systematic review examined the evidence base of fraction interventions for elementary level students identified as struggling math learners. Twelve studies met inclusion criteria and were reviewed for (a) instructional focus (b) instructional components, and (c) effectiveness of the intervention on fraction performance. The majority of studies had a primary instructional focus on conceptual knowledge of fraction learning. Results of the study also indicated that all interventions included multiple evidence‐based instructional components (e.g., concrete and visual representations, range and sequence of examples, etc.). These multicomponent interventions improved performance on a variety of proximal fraction outcome measures. Intervention effects were mixed for generalized outcome measures and minimal for distal outcome measures. Limitations, implications for practice, and future research directions are discussed.     

Not even well begun: women in computing courses

Concern is often expressed about the underrepresentation of women in scientific and technological programmes in higher education. This concern prompted us to undertake a study of Australian computing science courses at the top level of professional accreditation. Our concern was with the numbers of women enrolling and how women fared in the early stages of the courses. The work from our study provides the basis for this paper in which we examine the ways in which women tend to be disadvantaged in computing courses. We discuss the issues both in terms of factors which are identifiable from the perspective of the discipline at large and those which are associated specifically with the presentation of courses within institutions of higher education. At the discipline level we discuss the apparent technology-centredness of computing, the emphasis accorded mathematics as well as narrow problem solving skills and the undervaluing of broadly based problem solving and communication skills. In the institutional context, our concerns lie with the consequences of gender stereotyping on attitudes and interactions, the significance of prior computing knowledge and experience as well as of mathematical background, and the way the curriculum is structured and organised.     

Going Global: The implications for students with a disability

Equitable educational access is a hallmark of truly international universities, and higher education institutions operating in an international context have a responsibility to incorporate the principles of equity and justice espoused under international conventions. This paper considers the implications of internationalisation for students with a disability, it focuses on study abroad, exchange and international students travelling to Australia, and Australian students travelling to universities outside Australia. The paper considers the curriculum implications of the internationalisation of education for students with a disability and utilises Murray-Seegert's (1993) ecological theory of diversity to explore the ways cultural factors affect opportunities for inclusion of students with a disability in the higher education sector. The authors also examine the effect of the advance in information technology, the implications for inclusive curriculum, and the complexities inherent in cross-cultural expectations on students with a disability.     

Performing property cycles

Economists characterize fluctuations in property markets as ‘cyclical’ in that characteristics repeat and recur instead of being temporally isolated or random. I argue that cycle metaphors naturalize change and distract us from the social and institutional relations underpinning transformation in local property markets. I emphasize the performative nature of cycles by focusing on the networks of actors – brokers, appraisers, investors, and planners – that move capital through the built environment, articulating arguments for its free passage, identifying inflexion points, and temporarily stabilizing the meanings associated with individual buildings, submarkets, and periods. Drawing from a case study of an office development cycle in downtown Chicago (1998–2009), I argue that cycles can be treated not only as metaphors that describe economic processes, but also as socially effective constructions in their own right. Specifically, I consider three ways in which actors perform cycles, including (1) professionals’ use of market devices that contain within them assumptions regarding the proper timing of (dis)investment; (2) the existence of incentives for herding among professionals that draw them to and away from assets at roughly the same times; and (3) the importance of cycle thinking in instilling the confidence necessary to speculate on an unknown future.     

The fluid and electrolyte balance of New Zealand European and Māori/Pacific Island athletes: An observational study

Observational research on professional athletes from the USA suggests differences may exist in sweat sodium loss based on ethnic differences. The New Zealand (NZ) sporting population is mainly of European or Māori/Pacific Island origin. Therefore, this study aimed to describe the fluid-electrolyte balance of athletes by ethnicity. A total of 20 Māori/Pacific Islanders (MP; body mass 100.97 ± 13.05 kg) and 29 NZ European (NZE; body mass 89.11 ± 11.56 kg) elite male athletes were recruited. Sweat rates were determined by body mass change during a 1-h spin cycle exercise session, during which fluid intakes and heart rate were recorded. Sweat samples were analysed for sodium concentration. Mean ± SD sweat sodium concentrations were 73.4 ± 27.2 mmol·L^?1 and 55.5 ± 26.8 mmol·L^?1 for the MP and NZE groups, respectively (p = 0.070). Sweat rate was 0.93 ± 0.26 L·h^?1 for the MP group and 0.89 ± 0.33 L·h^?1 for the NZE group (p = 0.357). Fluid intake was 1.05 ± 0.48 L and 0.93 ± 0.49 L for MP and NZE, respectively (p = 0.395). Half of the MP group gained weight during the exercise session compared to 37% of the NZE group. Pre-exercise urine specific gravity was significantly lower amongst the NZE group (1.016 ± 0.009 g mL^?1) than the MP group (1.024 ± 0.008 g mL^?1) p = 0.001. There was no significant difference in heart rate between the groups, p = 0.082. Hydration practices of athletes in NZ may differ by ethnicity, and this may highlight the need for more targeted education by ethnicity.
